Study on Fuzzy Reliability of the Gravity Retaining and Protecting Structure for Foundation Pit

Abstract:

The major instable modes of the gravity retaining and protecting structure for foundation pit are overturning and slipping. Because of the stability of these geotechnical problems is affected by many uncertain factors, the stability analysis of them should be involved in the scope of the fuzzy and random event. Therefore, based on the theory of probability and fuzzy mathematics, the random and fuzzy characteristics were took into account, the calculating model of the fuzzy reliability of the gravity retaining and protecting structure for foundation pit was established. Through an engineering example’s calculating analysis of its overturning and slipping instable modes, the fuzzy instable probability and reliable index are calculated, some relevant conclusions are acquired via comparing with the traditional safety-coefficient method, and the feasibility of the fuzzy reliability method is testified.
